Nano guardians of the heart: A comprehensive investigation into the impact of silver nanoparticles on cardiovascular physiology.

Globally, cardiovascular diseases (CVDs) constitute the leading cause of death at the moment. More effective treatments to combat CVDs are urgently required. Recent advances in nanotechnology have opened the door to new avenues for cardiovascular health treatment. Silver nanotechnology's inherent therapeutic powers and wide-ranging applications have made it the center of focus in recent years. This review aims to analyze the chemical, physical, and biological processes ofproducing AgNPs and determine their potential utility as theranostics. Despite significant advances, the precise mechanism by which AgNPs function in numerous biological systems remains a mystery. We hope that at the end of this review, you will better understand how AgNPs affect the cardiovascular system from the research done thus far. This endeavor thoroughly investigates the possible toxicological effects and risks associated with exposure to AgNPs. The findings shed light on novel applications of these versatile nanomaterials and point the way toward future research directions. Due to a shortage of relevant research, we will limit our attention to AgNPs as they pertain to CVDs. Future research can use this opportunity to investigate the many medical uses of AgNPs. Given their global prevalence, we fully endorse academics' efforts to prioritize nanotechnological techniques in pursuing risk factor targeting for cardiovascular diseases. The critical need for innovative solutions to this widespread health problem is underscored by the fact that this technique may help with the early diagnosis and treatment of CVDs.

Computational Exploration of Anti-Cancer Potential of GUAIANE Dimers from Xylopia vielana by Targeting B-Raf Kinase Using Chemo-Informatics, Molecular Docking, and MD Simulation Studies.

BACKGROUND: Natural products from herbs are abundant and display powerful anti-cancer activities. OBJECTIVES: In the current study, B-Raf kinase protein (PDB: 3OG7), a potent target for melanoma, was tested against two guaiane-type sesquiterpene dimers, xylopin E-F, obtained from Xylopia vielana. METHODS: In this work, a systematic in silico study using ADMET analysis, bioactivity score forecasts, and molecular docking along with its simulations was conducted to understand compounds' pharmacological properties. RESULTS: During ADMET predictions of both the compounds, xylopin E-F displayed a safer profile in hepatotoxicity and cytochrome inhibition, and only xylopin F was shown to be non-cardiotoxic compared to the FDA-approved drug vemurafenib. Both the compounds were proceeded to molecular docking experiments using Autodock docking software, and both the compounds, xylopin E-F, displayed higher binding potential with -11.5Kcal/mol energy compared to control vemurafenib (-10.2 Kcal/mol). All the compounds were further evaluated for their MD simulations, and their molecular interactions with the B-Raf kinase complex displayed precise interactions with the active gorge of the enzyme by hydrogen bonding. CONCLUSION: Overall, xylopin F had a better profile relative to xylopin E and vemurafenib, and these findings indicated that this bio-molecule could be used as an anti-melanoma agent and as a possible anti-cancer drug in the future. Therefore, this is a systematically optimized in silico approach for creating an anti-cancer pathway for guaiane dimers against the backdrop of its potential for future drug development.

An Overview of the Mechanisms of Marine Fungi-Derived Anti-Inflammatory and Anti-Tumor Agents and their Novel Role in Drug Targeting.

Marine fungi with their successful pharmacological effects were considered to be the treasure of ocean medicines concerning the striking ability of their secondary metabolites. Literature over literature has been published on fungi derived bioactive molecules to probe its therapeutic potential. Marine fungi have an implicit to cede future medicines against life-threatening diseases, such as cancer and several emerging inflammations. The biological actions of many marine fungi-derived secondary metabolites are still unlocked, for an assorted number of bioactive compounds by which they interact with human diseases are discussed here with comprehensive diagrams. This knowledge is one of the main tracks to be established specifically for the successful transformation of bioactive compounds to medicines. Marine fungi produce a diverse range of biochemical substances with precious carbon scaffolds, which are the main component interplaying with human diseases at distinctive spots. Specific diseases having a flair to fight at distinctive targets within the body can lead to a new trend of raising the chances of developing targeted drugs.

Guaiane-type sesquiterpenoids from Cinnamomum migao H. W. Li: And their anti-inflammatory activities.

The phytochemical assessment of Cinnamomum migao H. W. Li fruits illustrated the isolation and identification of ten undescribed guaiane-type sesquiterpenoids "miganoids A-J″ and one undescribed sesquiterpene "7(S)-(hydroxypropanyl)-3-methyl-2-(4-oxopentyl) cyclohex-2-en-1-one". The extensive analysis of HRESIMS, 1D NMR, 2D NMR, experimental circular dichroism (ECD), and calculated (ECD) analysis entirely corroborated the configuration and confirmation of these isolated compounds. Moreover, the anti-inflammatory properties of the reported compounds were established by determining the LPS induced nitric oxide production. In the current study, miganoid C is testified the most active compound with about 89% NO inhibition. Additionally, miganoids C, E, and G also exhibited moderate inhibitory effects against the pro-inflammatory cytokines (TNF-α, IL-1ß, and IL-6). The IC50 values for miganoid C and miganoid G were determined as 19.4 and 14.5 µΜ against TNF-α mRNA, respectively.

Phytochemical study of Ligularia subspicata and valuation of its anti-inflammatory activity.

This report illustrated isolation and identification of 42 compounds comprising five (spicatainoids A-E) undescribed eremophilanolide type sesquiterpenoids and one undescribed nor-eremophilane (spicatainoid F) from Ligularia subspicata.. Among all the isolated new compounds, 4 is reported as the first enantiomeric form of novel eremophilanolide type sesquiterpenoid. Comprehensive analysis of HRESIMS, 1D/2D NMR, experimental circular dichroism (CD), calculated ECD analysis, and X-ray crystallographic (XRD) analysis validated the complete configuration and confirmation of these isolated compounds. All the isolated compounds were tested for the anti-inflammatory potential by measuring the amount of nitric oxide production. Among the tested compounds, 4 was the most effective with 90% NO-inhibition activity. Compounds 1, 2, 3, 9, 10 18, 29, 34, 35 exhibited moderate inhibitory effects against the production of NO, while other compounds displayed no activity even at the concentration of 50 µM. Additionally, compounds 1, 3 and 4 presented moderate anti-inflammatory activity by inhibiting the release of pro-inflammatory cytokines (TNF-α, IL-1ß, and IL-6) in LPS-stimulated N9 cells. The IC50 values of compounds 1, 3 and 4 were calculated 39.6 ± 2.7, 42.5 ± 3.8 and 27.60 ± 1.9 µΜ.
